Design
The
Don Valley Mk1 Chain is a positive
improvement over traditional design, and has resulted from many years
practical experience, designing and building scraper conveyors plus an
extensive knowledge of the operational problems associated with the
transportation of bulk materials where particularly arduous conditions exist.
Mk1 Chain offers the following advantages to the user :-
 |
Forged
Cross Bar Connecting Links
form an integral part of the chain and provide a strong and reliable
connection to the flights, eliminating the possibility of weld failure at
this critical point. |
 | Easily
Replaceable Cross Bars
are tailored to suit individual requirements. These are bolted direct to
the forged connectors with High Tensile Bolts and Re-useable Locknuts. The
interfaces of the mating surfaces are also chemically bonded together
during assembly to provide enhanced security. |
 |
Rationalisation of Spares.
Capital outlay and replacement costs are minimised since :-
● Chains
and Connectors are symmetrical and not handed. Provided that the Cross
Bar pitch is constant, a single strand of chain held in stock will serve
as a spare for any number of conveyors regardless of flight bar length
or design.
●
In the
event of localised damage, the individual component can easily be
replaced.
●
Assembled lengths of chain are connected on site by cold riveting. |
 | Cross Bar Fixing
Kits with full instructions are available to enable the customer to
undertake refurbishment or repair work. |
